Astronomical Observatory
Founded in 1894, Lowell Observatory is one of the oldest private observatories in the United States and a Registered National Historic Landmark. Recognized as an Arizona Treasure, it was named one of the World’s 100 Greatest Places by TIME in 2025 and honored as the nation’s Best Science Center by Newsweek. Located in Flagstaff, the world’s first International Dark Sky City, Lowell offers awe-inspiring views of the cosmos through state-of-the-art telescopes and with the naked eye. On clear nights, observe the Moon, planets, and deep-sky objects through the historic 24-inch Clark Refractor or the six cutting-edge telescopes of the Open Deck Observatory. Visitors can also explore the new 40,000-square-foot Astronomy Discovery Center, featuring a rooftop open-air planetarium, an immersive theater, a hands-on children’s exhibit hall, a café, and more. Every space is designed to inspire curiosity, wonder, and a deeper connection to the universe. Lowell offers a wide range of live science talks and guided tours that span from the observatory’s pioneering discoveries to the forefront of modern astronomical research.
